Recognize some of them? Well. starting today, August 24, the old Shogakukan building’s graffiti art will temporarily be open for public viewing. This once in a life-time event however only lasts until tomorrow, August 25, but it does promise to take you back to some really old mangas like Doraemon, Ranma 1/2 and Honō no Tenkōsei.

The event, called Graffiti Tournament! Thank you Shogakukan building! started when 25 manga artists led by Doraemon’s Fujiko Fujio A drew some manga art in the hallowed walls of the old building. The artists involved include Naoki Urasawa (20th Century Boys), Kazuhiko Shimamoto (Honō no Tenkōsei), Masami Yuki (Birdy the Mighty/ Patlabor), Mine Yoshizaki (Sgt. Frog), Kuromaru (Shin Kurosagi) and many many more.

The viewing time will be from 9:00 am-9:00 pm with ticket distributions starting at 8:15. Photography is allowed but taking videos as well as food and drinks are not.
